Description

Technical Field

[0001] This invention belongs to the field of mahjong entertainment equipment, and relates to mahjong machines, and more particularly to an integrated control panel and shuffling system in a mahjong machine, as well as a mahjong machine containing the integrated system. Background Technology

[0002] Automatic mahjong machines typically include a control panel for users to input commands and / or check usage status. Furthermore, the shape of this control panel usually matches the mahjong tile slot on the table, opening and closing it via a lifting motion. For example, when the control panel rises, a gap is exposed between it and the slot, allowing the user to push the mahjong tiles through this gap, where they fall into the shuffling tray below for shuffling. When the control panel descends, it returns to its level position with the table, closing the slot.

[0003] The accuracy of the lifting position of the control panel is very important for the user experience of the mahjong machine, especially the lowering position that closes the push-in port. If the height is not appropriate when it descends to the end of its travel, it will cause a gap between the control panel and the push-in port, which is not only unsightly, but also poses a risk of dust and debris falling in.

[0004] To facilitate control of the lowering position of the control panel, some existing mahjong machines can limit the lowering position of the control panel. For example, CN201710626792.7 discloses a central lifting mechanism for a mahjong machine, in which a lifting rod limiting component is provided on the lifting rod of the control panel. Such a lifting rod limiting component can limit the lifting rod, but its limiting height is fixed, making it inconvenient to adjust the lowering position of the control panel during installation or maintenance. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an integrated system for an operating panel and a shuffling mechanism, installed in a mahjong machine. The system comprises an operating panel mechanism, a shuffling mechanism, and a mounting base. The operating panel mechanism has a height-adjustable operating panel and an adjusting limit sleeve located below the operating panel for adjusting its height during descent. The shuffling mechanism has a shuffling disc capable of rotating to shuffle the mahjong tiles and a fixing cap for securing the shuffling disc. The mounting base has a first threaded portion and a second threaded portion located below the first threaded portion. The adjusting limit sleeve is threaded onto the first threaded portion, and the fixing cap is threaded onto the second threaded portion. An elastic locking structure restricts the relative rotation of the adjusting limit sleeve and the fixing cap.

[0006] The operating panel and shuffling integrated system provided by the present invention may also have the following technical features: multiple longitudinally extending engaging protrusions are distributed on the adjusting limit sleeve, and an elastic piece is connected to the fixing cap. The inner side of the elastic piece is provided with multiple longitudinally extending engaging grooves, which engage with the engaging protrusions to form an elastic engaging structure.

[0007] Furthermore, the above-mentioned integrated operating panel and shuffling system provided by the present invention may also have the following technical features: the lower end of the adjusting limit sleeve has a vertically downward extending extension, the engaging protrusion extends at least on the extension, the fixing cap has a receiving groove for accommodating the extension, the outer wall of the receiving groove is provided with a recess, and the elastic sheet is connected in the recess.

[0008] In addition, the operating panel and shuffling integrated system provided by the present invention may also have the following technical feature: the thread direction of the first threaded part is opposite to that of the second threaded part.

[0009] In addition, the integrated system for operating panel and shuffling provided by the present invention may also have the following technical feature, wherein a vertical tube for supporting the operating panel is movably inserted inside the mounting base.

[0010] Furthermore, the above-mentioned integrated system for operating panel and shuffling provided by the present invention may also have the following technical features: the operating panel mechanism further includes a lifting drive unit for raising and lowering the operating panel. The lifting drive unit includes a lifting drive seat fixedly installed at the bottom end of the riser, a lifting drive component having a drive block at one end that contacts the bottom surface of the lifting drive seat, and a lifting drive motor. The other end of the lifting drive component is installed on the output end of the lifting drive motor.

[0011] In addition, the operating panel and shuffling integrated system provided by the present invention may also have the following technical features, wherein the shuffling panel is rotatably mounted on the mounting base by bearings, has a bearing seat for mounting the bearing, and the lower surface of the fixing cap abuts against the upper surface of the inner ring of the bearing, thereby pressing the bearing into the bearing seat.

[0012] Furthermore, the above-mentioned integrated operating panel and shuffling system provided by the present invention may also have the following technical feature: the pressing rotation direction of the fixing cap is the same as the rotation direction of the shuffling panel.

[0013] The present invention also provides a mahjong machine, characterized in that it includes an operation panel and a shuffling system as described in any of the above.

[0014] Invention Function and Effect

[0015] According to the integrated control panel and shuffling system and mahjong machine provided by the present invention, since the mounting base is provided with a first threaded part and a second threaded part, the adjusting limit sleeve is threadedly connected to the first threaded part and the fixing cap is threadedly connected to the second threaded part, and an elastic locking structure is provided between the adjusting limit sleeve and the fixing cap, the two do not rotate relative to each other when no external force is applied, but can rotate relative to each other when an external force is applied. Therefore, on the one hand, the height position of the adjusting limit sleeve can be maintained during normal use, so that the lowering position of the control panel does not change. On the other hand, it is only necessary to twist the adjusting limit sleeve to overcome the elastic force and disengage the elastic locking structure to allow the adjusting limit sleeve to rotate, thereby realizing the adjustment of the limit height, that is, realizing the adjustment of the height position when the control panel descends. This adjustment process can be achieved without removing the control panel, so this adjustment is very easy to achieve during installation and maintenance. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of the present invention will be described below with reference to the accompanying drawings and examples.

[0029] <Example>

[0030] Figure 1 , Figure 2 This is a structural diagram of a mahjong machine according to an embodiment of the present invention.

[0031] like Figure 1-2 As shown, this embodiment provides a mahjong machine 100 for automatically shuffling and loading mahjong tiles 200, including a tile loading mechanism 101, an operation panel mechanism 102, a table frame mechanism 103, and a shuffling mechanism 107.

[0032] The table frame mechanism 103 includes an outer frame 104, a tabletop 105 mounted on the outer frame 104, and a table base 106 supporting the tabletop 105 and other mechanisms. The bottom of the table base 106 is provided with table legs for support on the ground, and the middle of the tabletop 105 is provided with a push-in slot 1051 for the user to push in mahjong tiles 200 when shuffling is required. Figure 1 , Figure 2 Table legs were omitted in all of them. Figure 2 The outer frame 104 and the tabletop 105 are further omitted.

[0033] Figure 3 This is a structural diagram of a mahjong machine in an embodiment of the present invention, omitting the card-adding mechanism.

[0034] like Figure 1-3 As shown, the control panel mechanism 102 is located in the middle of the tabletop 105, and includes a control panel 21 that can be raised and lowered for users to input operation commands, a support member for supporting the control panel 21, a limiting unit for limiting the height of the control panel 21 when it is lowered, and a lifting drive unit for driving the raising and lowering of the control panel 21. The shape of the control panel 21 is adapted to the push-in port 1051. When it is not raised, it closes the push-in port 1051. When it is raised, it exposes the push-in port 1051, allowing the user to push the mahjong tiles 200 in.

[0035] The shuffling mechanism 107 is used to receive and shuffle the mahjong tiles 200 after use. It includes a shuffling plate 71, a shuffling plate mounting unit for mounting the shuffling plate 71, a shuffling plate driving unit for driving the shuffling plate 71 to rotate, and a shuffling plate height adjusting unit for adjusting the height of the shuffling plate 71.

[0036] In this invention, the mounting structure of the operating panel 21 and the mounting structure of the shuffling panel 71 are realized through a common mounting base, thereby the operating panel mechanism 102, the shuffling mechanism 107 and the common mounting base constitute an integrated operating panel and shuffling system.

[0037] The following description, in conjunction with the accompanying drawings, illustrates the common mounting base and the corresponding mounting structure.

[0038] Figure 4 yes Figure 3 Longitudinal sectional view of the middle structure, Figure 5 yes Figure 3 The structural diagrams of some components, such as the shuffling plate and the control panel, are omitted from the text.

[0039] like Figure 3-5 As shown, the mounting base 108, serving as the aforementioned common mounting base, is approximately cylindrical. Its upper end has a first external thread portion 81 and a second external thread portion 82 arranged sequentially from top to bottom. The outer diameter of the first external thread portion 81 is smaller than that of the second external thread portion 82, and the thread directions of the first and second external thread portions 81 are opposite. The mounting base 108 is fixedly mounted on the table base 106. Specifically, the table base 106 has a downwardly recessed center, slightly larger than the shuffling plate 71, allowing the shuffling plate 71 to be accommodated within the recess. The bottom of this recess is a support plate 1061, and the mounting base 108 is fixedly mounted at the center of this support plate 1061. Additionally, in this embodiment, a cover 1062 is installed below the support plate 1061 to cover and shield the components below the support plate 1061.

[0040] like Figure 4-5 As shown, the support member that supports the operating panel 21 is a vertical pipe 22, which is movably inserted into the mounting base 108, and the operating panel 21 is fixedly installed at the top of the vertical pipe 22.

[0041] Figure 6 This is a structural diagram of the lifting drive unit according to an embodiment of the present invention.

[0042] like Figure 6 As shown, the lifting drive unit includes a lifting drive motor 231, a lifting drive component 232, and a lifting drive base 233.

[0043] The lifting drive motor 231 is fixedly mounted below the support plate 1061 via a motor mounting bracket 2311.

[0044] One end of the lifting drive component 232 is fixedly installed on the output end of the lifting drive motor 231, and the other end is provided with a drive block 2321.

[0045] The lifting drive base 233 is fixedly installed at the bottom end of the riser 22, and its bottom surface is in contact with the drive block 2321. When the lifting drive component 232 rotates under the drive of the lifting drive motor 231, the end where the drive block 2321 is located can swing up and down, causing the riser 22 to rise or fall.

[0046] The control panel limiting unit includes an adjusting limiting sleeve 24, which is a frustoconical cylindrical shape with an internal thread on its inner surface. This internal thread connects the sleeve to the first external thread portion 81. The upper end of the riser 22 passes through the fixed base 108 and is positioned above it, causing the control panel 21 to be positioned above the adjusting limiting sleeve 24. When the control panel 21 descends under the action of the lifting drive unit, the top end of the adjusting limiting sleeve 24 contacts the bottom end of the control panel 21, limiting its descent position. By rotating the adjusting limiting sleeve 24, the height of its top end can be adjusted, thereby adjusting the required high or low position of the control panel 21 during descent. The specific adjustment method will be detailed later.

[0047] Figure 7 This is a structural diagram of the shuffling disc according to an embodiment of the present invention.

[0048] like Figure 7 As shown, the shuffling disc 71 includes a disc body 711, a sliding layer 712, and multiple partition blocks 713. The disc body 711 has a sliding part 7111, a stopping part 7112, and a blocking part 7113.

[0049] The sliding section 7111 is a truncated cone shape, approximately like a conical hat, located below the push-in port 1051. It is used to receive the mahjong tiles 200 falling from the push-in port 1051 and allow these mahjong tiles 200 to slide on it. The middle part of the sliding section 7111 is used to connect with the shuffling tray mounting unit, and has a bearing seat 7114 that is recessed downward to form an annular groove. The bearing seat 7114 has an approximately L-shaped cross section, with side walls extending downward from the inner edge of the sliding section 7111 and a bottom wall extending horizontally inward from the side walls.

[0050] In this embodiment, the upper surface of the sliding part 7111 is inclined, that is, in the normal installation and use state, the height of the outer part of the sliding part 7111 is lower than the height of the part far from the inner side, and the inclination angle is 30°. When the mahjong tiles 200 are pushed in through the push-in port 1051, they can slide down on the sliding part 7111, and this scattering and sliding process serves to shuffle the mahjong tiles 200.

[0051] The stop plate portion 7112 is connected to the outside of the sliding portion 7111, extending outward around the sliding portion 7111 to form a ring. In this embodiment, the upper surface of the inner part of the stop plate portion 7112 (i.e., the part connected to the sliding portion 7111) has a small inclination, while the outer part does not have an inclination and is horizontal.

[0052] The blocking part 7113 is located on the outer edge of the stop part 7112, and extends upward from the outer edge to form a ring.

[0053] The sliding layer 712 is laid on the sliding part 7111 and the stop part 7112. In this embodiment, the sliding layer 712 is divided into multiple block-shaped components, including multiple first sliding layer parts 7121 laid on the sliding part 7111 and multiple second sliding layer parts 7122 laid on the stop part 7112, wherein the number of first sliding layer parts 7121 and second sliding layer parts 7122 is the same (8 each) and they correspond one-to-one.

[0054] The first sliding layer 7121 has a curved fan shape, and each first sliding layer 7121 is curved to the same side along the circumference. The two side edges of adjacent first sliding layer 7121 match each other, so that the gaps between each first sliding layer 7121 present multiple spiral lines evenly arranged.

[0055] The second sliding layer 7122 is fan-shaped, with its inner edge located at the junction of the sliding part 7111 and the stop part 7112, corresponding to the outer edge of the first sliding layer 7121 and having a certain gap between them; the outer edge of the second sliding layer 7122 extends to the stop part 7113 and contacts the stop part 7113.

[0056] Both the first sliding layer 7121 and the second sliding layer 7122 are made of composite fiber material fabric. In this embodiment, they are made of the napped surface layer of nylon hook and loop fasteners.

[0057] There are eight partition blocks 713, evenly distributed circumferentially on the outer part of the stopping section 7112. In this embodiment, the eight partition blocks 713 are located between the gaps of two adjacent second sliding layers 7122. Each second sliding layer 7122 also has notches on both sides corresponding to the partition blocks 713, so that the partition blocks 713 can be exposed. Each partition block 713 is a "tough rib" block, that is, made of rubber or plastic material with a certain degree of elasticity, which can block the mahjong tiles 200 to facilitate shuffling, and at the same time reduce collision noise.

[0058] like Figure 4-5 As shown, the shuffling disc mounting unit includes a bearing 721 and a fixing cap 722.

[0059] The bearing 721 is fitted in the middle of the mounting base 108. Its inner ring is adapted to and interference-fitted with the outer surface of the mounting base 108, and its outer ring is adapted to and interference-fitted with the inner surface of the bearing housing portion 7114. Thus, the shuffling disc 71 is rotatably mounted on the mounting base 108 via the bearing 721.

[0060] The fixing cap 722 is generally hollow and frustoconical in shape, located above the shuffling disc 71, and is installed on the mounting base 108 by threaded connection with the second external thread portion 82. The lower surface of the fixing cap 722 abuts against the upper surface of the inner ring of the bearing 721, thereby pressing the bearing 721 into the bearing seat portion 722 and preventing it from loosening. In addition, in this embodiment, the pressing rotation direction of the fixing cap 722 (i.e., the downward rotation direction) is the same as the rotation direction of the shuffling disc 71. Therefore, even if the shuffling disc 71 rotates and comes into contact with the fixing cap 722, generating a certain driving force, this force can still cause the fixing cap 722 to have a downward pressing rotational movement tendency, which can keep the fixing cap 722 in a pressed state during use and prevent it from loosening.

[0061] Figure 8 yes Figure 4 Enlarged view of part A.

[0062] like Figure 8 As shown, the lower end of the adjusting limit sleeve 24 is provided with a vertically downward extending portion 241, and the fixing cap 722 is provided with a receiving groove 7221 that accommodates the extending portion 241. Specifically, the outer wall of the receiving groove 7221 is higher and is formed around the periphery of the extending portion 241, while the inner wall is lower. The inner surface of the inner wall is the internal thread used for threaded connection with the second threaded portion 82.

[0063] Figure 9This is an exploded structural diagram of the mounting base, adjusting limit sleeve, and fixing cap according to an embodiment of the present invention.

[0064] like Figure 8-9 As shown in this embodiment, multiple engaging protrusions 242 extending longitudinally along the outer surface of the adjusting limiting sleeve 24 are evenly distributed on the outer surface, and these engaging protrusions 242 all extend to the extension portion 241.

[0065] Figure 10 This is a structural diagram of the fixed cap according to an embodiment of the present invention.

[0066] like Figure 8-10 As shown, the upper end of the outer wall of the receiving groove 7221 is provided with a recess 7220, and an elastic piece 7222 is connected inside the recess 7220. The inner surface of the elastic piece 7222 (i.e., the surface facing the adjusting limit sleeve 24) has a protrusion, and the protrusion has a plurality of engagement grooves 7223 that extend substantially longitudinally. The size of the engagement grooves 7223 and the spacing between adjacent engagement grooves 7223 are matched with the size and spacing of the engagement protrusion 242, so that they can engage with the engagement protrusion 242. Since the fixing cap 722 is made of plastic or other materials, the elastic piece 7222 itself has a certain elasticity and can apply a certain pressure to the engagement grooves 7223, so that the engagement grooves 7223 and the engagement protrusion 242 remain engaged when no external force is applied, that is, the two are elastically engaged, forming an elastic engagement structure. Therefore, when there is no external force, the relative rotation between the fixing cap 722 and the adjusting limit sleeve 24 in the circumferential direction is restricted by their locking action, that is, the fixing cap 722 and the adjusting limit sleeve 24 cannot rotate relative to each other.

[0067] With the bearing 721 and the shuffling disc 71 installed on the mounting base 108, when the operator (i.e., the technician who installs or maintains the mahjong machine 100) needs to further install the fixing cap 722 and the adjusting limit sleeve 24, the fixing cap 722 can be screwed onto the second external thread 82 and tightened to press it against the inner ring of the bearing 721; then, the adjusting limit sleeve 24 can be screwed onto the first external thread 81, and the adjusting limit sleeve 24 can be rotated and stopped at a suitable height position according to the position required when the operating disc 21 is lowered.

[0068] During the installation process or the adjustment of the height of the adjusting limit sleeve 24, when the operator rotates the adjusting limit sleeve 24, the force applied by the operator can overcome the elastic force of the elastic piece 7222, and the engaging groove 7223 and the engaging protrusion 242 can disengage, allowing the adjusting limit sleeve 24 to rotate relative to the fixing cap 722. When the operator stops rotating the adjusting limit sleeve 24, the elastic force of the elastic piece 7222 applies pressure to the engaging groove 7223, causing it to return to the engaging state with the engaging protrusion 242, thus restricting the relative rotation of the fixing cap 722 and the adjusting limit sleeve 24 again.

[0069] Therefore, the operator can easily adjust the height position of the adjusting limit sleeve 24, while the adjusting limit sleeve 24 will not rotate relative to the fixed cap 722 during normal use.

[0070] Furthermore, since the fixing cap 722 always tends to rotate and tighten under the action of the shuffling disc 71, it will basically not rotate during actual use. Correspondingly, the adjusting limit sleeve 24 will not rotate either, thus maintaining the upper position of the adjusting limit sleeve 24 unchanged. In addition, in this embodiment, the outer surface of the fixing cap 722 is also provided with multiple protrusions, which can increase the surface friction and facilitate the operator to tighten it; at the same time, the engaging protrusions 242 extend to the inclined part of the adjusting limit sleeve 24, which can also increase the surface friction and facilitate tightening.

[0071] The shuffling disc drive unit includes a shuffling motor 731, a shuffling output gear 732, a shuffling input gear ring 733, and an auxiliary gear 734.

[0072] The shuffling motor 731 is fixedly installed below the support plate 1061, and its output shaft passes through the support plate 1061 upward.

[0073] The shuffling output gear 732 is mounted on the output end of the shuffling motor 731, located below the shuffling disk 71.

[0074] like Figure 4 As shown, the lower surface of the sliding part 7111 is provided with a ring of teeth, namely the shuffling input ring 733. The shuffling output ring 733 is distributed in a ring around the bearing housing part 7114. The shuffling output gear 732 meshes with the shuffling input ring 733, so that the shuffling motor 731 can drive the shuffling disk 71 to rotate through the meshing relationship between the two.

[0075] In this embodiment, there are two auxiliary gears 734, each mounted on the table base 106 via a gear mounting bracket. The gear mounting bracket has a rotating shaft, on which the auxiliary gear 734 is rotatably mounted and meshes with the shuffling input gear ring 733. The two auxiliary gears 734 and the shuffling output gear 732 are arranged at equal intervals in the circumferential direction (i.e., 120° apart). Through the meshing of the two auxiliary gears 734 with the shuffling input gear ring 733, the rotation of the shuffling disk 71 can be made smoother and more stable.

[0076] like Figure 5 As shown, several shuffling plate height adjustment units 74 are evenly distributed circumferentially below the stop section 712.

[0077] Figure 11 This is a structural diagram of the shuffling plate height adjustment unit in this embodiment.

[0078] like Figure 11 As shown, the shuffling plate height adjustment unit 74 includes a height adjustment seat 741 and a roller 742.

[0079] The height adjustment seat 741 is fixed on the support plate 1061 and has a pair of spaced-apart seat plates 7411. Each seat plate 7411 has three height adjustment grooves 7412 of the same width but decreasing depth on its inner surface (i.e., the side surface facing the other seat plate 7411). The height adjustment grooves 7412 on the two seat plates 7411 are arranged opposite to each other, and the height adjustment grooves 7412 at opposite positions on the two seat plates 7411 have the same depth.

[0080] The rolling wheel 742 has a wheel body 7421 and a wheel axle 7422 disposed on the wheel body 7412. The diameter of the wheel axle 7422 is adapted to the width of the height adjustment groove 7412, and the distance between the two ends of the wheel axle 7422 is matched with the distance between the two opposite height adjustment grooves 7412, so that it can be placed into the two opposite height adjustment grooves 7412 respectively, so that the wheel body 7412 is located between the two seat plates 7411.

[0081] The wheel 7421 contacts the lower surface of the shuffling disc 711, providing support to the stopping section 712 during the rotation of the shuffling disc 71. Since the stopping section 712 is a certain distance from the bearing seat 714, it is prone to sinking under the weight when a large number of mahjong tiles 200 are piled on it. The support provided by the wheel 7421 prevents this sinking, making it easier for the loading mechanism 101 to pick up the mahjong tiles 200 from the stopping section 712. Furthermore, when the axle 7422 is placed in height adjustment slots 7412 of varying depths, the height at which the wheel 7421 supports the stopping section 712 also varies, allowing for slight adjustments to the height of the stopping section 712. This allows for adjustment of the support height to accommodate mahjong tiles of different sizes, further facilitating the picking-up action of the loading mechanism 101.

[0082] The mahjong machine 100 of this embodiment can be used by four users simultaneously. Accordingly, it is provided with four tile-feeding mechanisms 101, which are located at the four corners of the table base 106. Each tile-feeding mechanism 101 can pick up mahjong tiles 200 from the tile-stopping section 7112, stack the tiles, and raise the stacked mahjong tiles 200 to the table for the user to use. Its specific structure and working principle can adopt existing technology, and will not be described in detail here.

[0083] Functions and effects of the embodiments

[0084] According to the operation panel, shuffling integrated system, and mahjong machine provided in this embodiment, since the mounting base 108 is provided with a first threaded part 81 and a second threaded part 82, the adjusting limit sleeve 24 is threadedly connected to the first threaded part, and the fixing cap 722 is threadedly connected to the second threaded part 82. Furthermore, an elastic locking structure is provided between the adjusting limit sleeve 24 and the fixing cap 722. When no external force is applied, the two do not rotate relative to each other, making it difficult for the adjusting limit sleeve 24 to rotate. When an external force is applied, relative rotation can occur, allowing the position of the adjusting limit sleeve 24 to be adjusted. Therefore, on the one hand, the height position of the adjusting limit sleeve 24 can be maintained during normal use, so that the lowering position of the control panel 1021 does not change. On the other hand, it is only necessary to twist the adjusting limit sleeve 24 to overcome the elastic force and disengage the elastic locking structure to allow the adjusting limit sleeve 24 to rotate, thereby realizing the adjustment of the high and low lowering position of the control panel 1021. This adjustment process can be achieved without removing the control panel 1021, so installation and maintenance are very easy to achieve.

[0085] In this embodiment, since the threads of the first threaded portion 81 and the second threaded portion 82 are in opposite directions, the aforementioned elastic engagement structure will not cause the adjusting limit sleeve 24 and the fixing cap 722 to rotate together, thus preventing them from loosening together. Furthermore, since the pressing rotation direction of the fixing cap 722 is the same as the rotation direction of the shuffling disc 71, the force generated when the shuffling disc 71 rotates and contacts the fixing cap 722 can keep the fixing cap 722 pressed during use, further preventing loosening.

[0086] In this embodiment, since the extension 241 of the adjusting limit sleeve 24 is provided with a locking protrusion 242, and the receiving groove 7221 that accommodates the extension 241 is provided with an elastic piece 7222, the locking groove 7223 on the elastic piece 7222 and the locking protrusion 242 together constitute an elastic locking structure. Therefore, elastic locking can be achieved without setting additional elastic components, making manufacturing and assembly easier.

[0087] Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the technical solutions without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of protection claimed by the present invention.

[0088] For example, in this embodiment, the engaging protrusion 242 on the extension 241 of the adjusting limiting sleeve 24 and the engaging groove 7223 on the elastic piece 7222 connected to the receiving groove 7221 together constitute an elastic engaging structure. As an alternative, the positions of the engaging protrusion 242 and the elastic piece 7222 can also be interchanged, that is, a recess is provided on the extension 241 and connected to the elastic piece 7222, and the engaging protrusion 242 is provided on the inner surface of the outer wall of the receiving groove 7221, as long as the engaging groove 7223 on the elastic piece 7222 and the engaging protrusion 242 can be arranged opposite each other and can engage with each other.

[0089] As a further alternative, the elastic locking structure can also take other forms. For example, a slot can be provided on one of the extension 241 and the receiving groove 7221, and a spring-loaded locking block can be fixedly provided on the other. This can also achieve the function of locking each other when no external force is applied, and not locking each other when external force is applied, allowing the adjusting limit sleeve 24 and the fixing cap 722 to rotate relative to each other.

[0090] In addition, in the embodiment, the threads of the first threaded portion 81 and the second threaded portion 82 are opposite in direction, making it difficult for them to loosen together. However, if the pressing rotation direction of the fixing cap 722 is the same as the rotation direction of the shuffling disc 71, the thread directions of the first threaded portion 81 and the second threaded portion 82 can also be set to be the same. Since the fixing cap 722 is not easy to rotate when pressed against the bearing 721 in this case, the adjusting limit sleeve 24 can also be prevented from rotating by the elastic locking action.
